chore: UI clarity improvements (#84)

## Summary

- Move quest failure explanation to a static note above the quest list (cards now show failure % only)
- Show zone unlock requirements (boss + quest) on the Boss and Quest panels, matching the existing Exploration panel behaviour
- Display combat power per adventurer on adventurer cards, alongside gold/s and essence/s
